The Duntech Speaker Thread

Recommended Posts

Nice looking speakers.

 

Perhaps they would sound better without all the hardware in the way though :-)

The Audio Engineering Society (Adelaide section) tonight. 

"Loudspeakers and the Time Domain Jack Davis FIEAust, CPEng, AES member St Pauls Creative Centre, (downstairs) Cnr Pulteney & Flinders St Adelaide 7:30pm, Tuesday April 16 th 2019. Join us for a cook's tour of Pulse Coherent Loudspeaker design with Jack Davis, former R&D Manager for Duntech Audio. In this talk Jack will take us through the journey that an aspiring loudspeaker designer would pursue if they wanted to achieve an accurate loudspeaker. The talk starts with the notion of what an accurate loudspeaker might be like and then follows the various problems that would have to be overcome and possible solutions that would have to be devised in the process of developing an accurate loudspeaker. The hypothetical walk through of the design process covers actual problems that arose during the development of the various Classic Series loudspeakers in the late 90's and how they were overcome using the tools and techniques of that time. Jack is currently a Lead Systems Engineer at Raytheon supporting project System Design and Analysis activities. He has held various other positions since his time at Duntech. He graduated from University of Calgary with Bachelor of Science Degrees in Physics and Mechanical Engineering"

I'd love to come. I took  over Jack's job at a consultancy at Vipac  when he first moved onto Duntech. It was from a goodbye BBQ for him that I first liked the idea of Duntechs and finally got my Crown Princes 25 years later! I just need to shift things around to get there. 

Edit.... I'm going if anyone else is interested in a lift from southern suburbs.

Hi and apology to anyone viewing the video of the AES Duntech presentation..  Another person I sent the file to found it stopped after ~ 25 minutes.  I just checked and it is the same for me too. According to my device the file was "modified" i.e. finished at 20:47 which is as I expected and after the presentation ended so I don't know where the rest is.
It is 96.8 MB.      If you have a clue about this, please let me know. Meanwhile I'll be onto google about it as the device I used was a chromebook.

Hi Guzzista, and all

I'm new here and have an ME850 driving a pair of Marquis PCL500' both in need of a little TLC but nice to listen to non the less.

I would be very interested in auditioning the new Duntech speakers.

 

Thanks.

@tosk see the GTG thread mate, audition for the new Senator Signature Series is on at my place Sunday the 26th of May from 2.00pm, Helensburgh.

Hmm.   I wonder if consideration has been given to acoustic absorption on the wall behind the equipment (as recommended by John Dunlavy) and also putting a mirror on the floor to determine where the speaker image (as seen from the listener's ears position) occurs. Then put e.g. a rug on the floor over the area. The floor looks so shiny that a mirror may not be necessary. I see a curtain by the window which can be drawn to reduce reflection which is good. Is there similar on the opposite wall? 

 

In the last picture, under the wall sockets, what is that box with the black shiny top?

Do you mean the box on the bottom shelf, if so that is the outboard crossover for the speaker.

It looks like it is on the floor & has an orange or light brown end.   There's a chunky white plastic thing on the side

I am guessing it could be a data port, but I can find out and get back to you.

It would be appreciated.  It is so huge.   I'm wondering if it is a UPS (uninterruptible power supply) in an audiophile no-expense-spared case.

      Item: Duntech Marquis Floorstanding Speakers
      Location: Len Wallis Audio HQ, 64 Burns Bay Road, Lane Cove.
      Price: $1000
      Item Condition: Fair Secondhand Condition
      Payment Method: Cash, Paypal, Credit Cards, PayPal
      Extra Info:
      Don't see these very often! Just traded Dutech Marquis Floorstanders. Performance wise they are excellent and have tested as such. We have just re-rolled all the drivers so there is certainly years of music life in them.
      The cabinets are in fair condition for the age of the speaker (+20years old). The plinths, which are not shown in the pictures, do have some moisture damage but could be restored by someone with some time to their former glory. 
      From Duntech's website:
      "The Marquis has a time aligned, five driver arrangement. The bass and mid-range drivers have diecast magnesium chassis. The bass drivers use a vented magnet system and feature a special, coated, pulp paper cone.
      The mid-range drivers are double magnet design and have rubber suspension for low resonance.
      The double chamber tweeter is dome type, with a fabric diaphragm and ferrofluid for efficient cooling and damping.
      The cabinet is designed to provide optimum rigidity and its size has been matched to the performance requirements of the drivers. All drivers have separate sealed enclosures.
      Acoustic felt is matched to the requirements of the loudspeaker and tailored to the geometry of the enclosure.
      The loudspeaker grill is covered with acoustically transparent cloth and the cabinet is hand finished in high quality wood veneers."
      Specifications:
      Frequency Response : Measured at 3.5M on the tweeter axis = 45Hz-20KHz ±2dB
      Efficiency: Referenced at 1M (3.3 ft) on tweeter axis with an input of 2.83 volts RMS (1 watt at 8 ohms)     92dB SPL
      Nominal Impedance: Variance     4 ohms
      Power Rating Peak power for 10 mS: 500 watts
      Recommended Amplifier Power: Minimum RMS per channel 60 watts
      Dimensions: 1490mm H x 272mm  w x 469mm D
      Weight: 53 kgs each
      Shipping: We will ship these anywhere in Australia - however due to the size and weight, shipping costs are extra and will be dependent on the purchasers location.

      Item: Duntech Barron Speakers
      Location: Melbourne / N.E. Victoria
      Price: $1400 . ( Donation to SNA if these sell)
      Item Condition: Very Good
      Reason for selling: Too many speakers! 
      Payment Method: Pickup - Cash, Paypal, EFT
      Extra Info: Purchased a few months ago for the Batmaqn . http://www.stereo.net.au/forums/topic/125485-fs-duntech-barons/?tab=comments#comment-1869039

       I purchased these Barron's from the above SNA member (great chap) a couple of months ago to have a listen to the Duntech sound. I think that represent great value for $1400.
       
      I really only grabbed these for a listen as they were not intended replace my main speakers and I seem to be struck down my the too many speaker diease! Every room I walk into has got more speakers in it. (I am sure I am not alone here ) 
      I think these would need a reasonable amp to drive them properly.  I would be happy to drop these off in Melbourne tomorrow or next week in Melbourne or in Adelaide as I am planning on a visit. Off course you're welcome to pick them up from N.E. Victoria.
       
      Please don't request the the grilles be removed as I don't know how the socks come off and the drivers are all in good condition.
